all whom it muy concern: le it lniown that l, JOHN Melt. AMES, a e tenel the United States, and e resident or Dongen Hills, Staten island,liiehmond eounty, and State ol N ew York, have invented certain new anduseful lniproveirients in Car-Underlranies, and do hereby declare thatthe `following is a full, clear, and exact description of the nivention,such as will enable oth-ers skilled in the art to which it appertuins tomake and use the same, reference beinghad to the accompanying drawings,forming part ol this speeilioation, in which- Figure .l is a plan viewol one half of a car underlfraine equipped with the invention Fig. is acentral longitudinal seo-tional view on line 2-2 ollllig. 1 Fig. 3 anend elevational view; llig. d is a transverse sectional view showing atthe .right hand portion a view taken on line Lie-l oi' liig. l and atthe left hand portion a view on line 5 5 ol llig.` l.

The obieet of the invention is to rovide a combination wood and .metalunder rame for railway cars wherein center sills, side sills andintermediate sills of' wood used in eoinbhiation witlidraft sills ofmetal, prei"- erably in relatively the plane of the car body bolster,extending from end to end of vthe car while needle beams, recessed.' toreceive said drai't sills, with queen posts and truss i'ods'eooperate tosupport the load and transmit boiling and pulling stresses.

ln the drawings 5 idicates the center sills 3 fl intermediate sills; 7side slllls; 8 end sills and E) bolstersvall aeeording Yto stan( ardconstr'uetion said longitudinal. sills being of wood and beingpreferably continuous from end sill to yend sill. The bolster may be ofany eon'venient type but for convenience l have illustrated a bolsterhaving` compression member il, tension member l2 and struts 13 above theside bearings 14 and fillers 15 kbetween the upper and ower llanges 16ol the rolled draft sill members 17, the said draft sills beingcontinuous and serving, with the fillers i5, as struts for saidbolster-s While castings i8 are connected to the webs of said draftsills and extend longitudinally thereof Iat each side of said holsters,as best shown inllig. 2v,- the said castings rising to the plane oi thetop or said bolster so as to serve as stons for said draft sills wherebybulling and pulling stresses are transmitted to said bolster. Thecastings i8 are unitary members having middle portions which. areperforated for rivets 19 which secure said castings to the webs of thedraft sills and have upwardly and downwardly projectin extensions 20-21between which rest tie upper and lower members of the bolster.

At Aconvenient distances apart are tie plates 22 and 23 respectivelyabove and below said draft sills and bolts 24 are passed throu 'h saidtie plates, the llanges of said draft si ls and through the center sillsthereby securing said members together. Needle beams 25 extendtransversely below .the longitudinal sills and are recessed as shown inFig. i (left) lfor the reception of the draft sills while queenrl posts26 with lateral llanges 27 are secured below said needle beams by meansol bolts 28 which pass through said flanges 27, the needle beams 25,tlie'ilanges 16 ot' said draft sills, through cover plates 29-let intorecesses in said needle bean-1s and center sills" and through saidcenter sills whereby said parts are secured in position. The struts orqueen )osts 26 below the intermediate sills and si e sills are bolted inposition by bolts 3() as shown.

lt will' be observed that the recesses in the needle beams are deeperthanare the draft sills which pass through said recesses, whereby thesaid needle beams serve assu )porting cross bearers for the longitudinalsi ls independently olf said draft sills, Thisis important in a combinedwood ani vnietgal under-- frame as it ermits shrinkage] of the woodmembers wit lout subjeetin-gthe draft sills to rtsains oi compression insupporting the load.

l/Vhat l olsiin is:
